Weighted Average Formula
Average Price = Total Investment / Total Shares = Σ(Price × Qty) / Σ(Qty). This is a weighted average — larger lots have more influence on the average.
Calculate the weighted average buy price of a stock across multiple purchase lots. Useful for staggered buying (averaging down), SIP in direct stocks, and portfolio cost tracking.
